CARRIEFrLOADER.

Application filed September 30 1907.

To all whom it concern:

Paul, in the county of Ramsey and State of Minnesota, have ointly invented new and useful Improvement 111 CarmenLoaders, 0t

, which the following is a specification.

Our invention relates to an improvedcan rier loader and has for its primary object a device of its kind which is adapted for packing boxes or packages of merchandise and loading them upon a carrier.

Heretofore the operation involved has been performed by hand and the purpose of this invention is to provide a simple and inexpensive device which will accomplish these results.

In the accompanying drawings, forming part of this specification, Figure l is a side elevation. of our invention; Fig 2 plan view, and Fig. 8 is another side elevation showing the platform on which the articles of merchandise are packed in its normal po sition.

Our invention in a general way is adapted for use in connection with gravity or power carriers, a portion of such being illustrated by A in the drawings, the particular form shown being adapted to convey articles by gravity from a higher to a lower level and having a pair of side rails 2 and 3 between which anti-friction rollers 4 are suitably journaled. 1 The side rails are supported at a suitable elevation by means of a horse 5. Adjoining this gravity carrier is our in proved loader B which consists of a platform 6 adapted to remain normally in horizontal position as shown in Fig. 3 when the boxes or packages are being packed and to tilt downwardly into the position shown in Fig. l and automatically place or shift the articles so packed upon the carrier. The platform is pivoted substantially midway between its ends upon vertical posts 7 which are held vertically in position by set screws 8 passing through the sides of: a horse The platform is made up of a pair of side rails 10 and 11 upon. which are suit-al y journaled in ball bearing sockets 12 a series of anti-friction rollers 13. The side bars 10 are tied together by means of N "we 2 it which is in Specification of Letters Patent.

i the form of a yoke, the ends oi. which have attached thereto by the pivot 19 a link 20 l which in turn is pivoted. at 21 to a trans verse receiver or transfer devic C. This receiver consists of a suitable frame 22 made up of longitudinal sides 2?) and 2a which are tied together by space bars 25. The space bars 25 carry short sections of rails 26 and upon the sides 23 and 2t and also upon the sectional rails 26 are suitably journaled antifriction longitudinal wheels 27. The sides 23 and 24 are formed with yoke-s or V shaped ofl'sets 28 below the inner rail .2 of the carrier A, and at their outer ends are pivoted at 29 to the outer rail 3 of the carrier A. In normal position the receiver rests horizontally as shown in Fig. 3 with the antifriction wheels 27 below the running sur face of the rollers l of the carrier.

- At the rear of its fulcrum support 16 the foot lever is pivotally connected with the forward end of the platform by means of a link 30 pivoted at 31 to the platform and at 32 to the lever, whereby, when the foot lever is depressed, the forward end of the platform will be tilted down, while the receiver C, being pivotally connected with the foot lever forwardly of the lever support 16, will in the same movement of the lever be tilted up upon its pivotal support 29, bringing the platform and receiver into alinei'nent, shown in Fig. i, so that they will form a continuous downwardly inclined runway to the outer rail 3 of the carrier A.

tened upon the carrier are a pair of horizontal. supports 33 upon which are adjust ably secured by means of set bolts 34; vertical supports 35 which carry upon their upper ends horizontal anti-friction stop wheels These wheels are freely jonrnaled upon said vertical supports and adapted to impede further progress of the articles of mercl'iandise down the 1 "u so that when said receiver lowerei into l posiion shova'n in hi". 3 the articles of l Incl. handise rest upon I e rollers 4,- or 1 carrier A and are free to travel bv ity l down same. The upper end o" T is provided with a pair of legs )tmtcd by the pivo' T upon of the platform to support end of the platform in horizontal t on noon the At the lower end of the receiver and fee power as desired.

boxes or packages are placed upon the platform B 'when the latter is in horizontal position, and packed, a table or bench D adjoining the parts being placed Within convenient reach of the operator for the purpose of holding the boxes to be packed; After such packing operation is completed the lever 17 is depressed and thebox which is packed runs by gravity down the platform and receiver until it impinges against the Stop wheels 36. Thereupon the lever 17 is released and the parts assume the p0sition shown in Fig. 3, the article resting upon the anti-friction rollers 4 of the carrier A down which it moves either by gravity or Having described our invention, what we claim as new and desire to protect by Letters Patent, is

1. A loader of the class set forth, comprising a suitable platform having antifrietion devices upon its surface, a suitable support upon which said platform is pivoted, a receiver atone end of said platform, a carrier co-acting vith said receiver, and means for simultaneously lowering one end of said platform and raising one end of said receiver, for the purposes specified.

2. Apparatus of the class set forth, comprising, in combination, a longitudinal carrier, a loading carrier, a receiver between the carriers and means for simultaneously raising said receiver and lowering said loading carrier.

3. A loader of the class set forth, comprising, in combination, a longitudinal gravity carrier, a transverse reeelvmg section of g 'avity carrier below the surface of said longitudinal carrier, a platform at one sideof said longitudinal carrier and adjoining said receiving section, and means for moving said transverse section and platform to cause them to coincide and form a continuous inclined way down which articlesof merchandise are adapted to run above said longitudinal carrier and be deposited upon said longitudinal carrier when said transverse section and platform assume normal position.

4. A loader of the class described, comprising a carrier, a loading platform associated therewith and tiltably mounted, a transfer device interposed between said carrier and said platform and also tiltably mounted, and means for simultaneously tilting the loading platform and the transfer device, whcrel'iy to bring the same into coincidence, and move the articles from the loading platform over the transfer device and onto the carrier.

5. A loader of the class described, comprising a carrier, a loading platform assoclated therewith, a support for said platform and upon which the latter is tiltably mounted, a transfer device interposed between the carrier and said loading platform and tiltably mounted upon said carrler, and means for simultaneously raisring said transfer device and lowering the contiguous end of the platform whereby to bring-the latter and the transfer device into coincidence, and thereby move the articles from the loading platform over the transfer device and onto the carrier.

6. A loader of the class described, comprising a carrier, a loading platform associated therewith, a support for said platform and upon which the latter is tiltably mounted, a transfer device interposed between said carrier and the loading platform and tiltably mounted in relation to the latter, a manually-operated lever fulcrumed upon the support of the loading platform, and connections between said lever and the loading platform and transfer device, whereby said lever is caused to simultaneously tilt the loading member and transfer device into coincident relation, and thereby move the articles from the loading platform over the transfer device and onto the carrier.

7. A loader of the class described comrisin a lon itudinal carrier a transverse receiving section of gravity carrier pivotally supported at its outer end upon the outer side of the longitudinal carrier, and

standing normally below the surface thereof. a platform at the inner end of said receiving section but standing normally above the same, and means operatively connected with the inner end of said receiving section. for tilting the same upwardly upon its pivotal support, whereby to bring the
